Abstract

A process for the separation of 2-methylalkanals from a mixture thereof with at least one alpha unbranched aldehyde thereof comprising distillation of said mixture in the presence of formaldehyde and an aldolization catalyst whereby the alpha unbranched aldehydes are converted to alpha alkylacrolein and the 2-methylalkanals are recovered in a high purity.
